Employees of Lawrence Livermore National Laboratory have ported Sun's/Oracle's ZFS natively to Linux. Linux already had a ZFS port in userspace via FUSE, since license incompatibilities between the CDDL and GPL prevent ZFS from becoming part of the Linux kernel. This project solves the licensing issue by distributing ZFS as a separate kernel module users will have to download and build for themselves.

Considering Oracle are developing BTRFS, and seemingly did so as a competitor to ZFS which they also now own... It would make a lot of sense for them to re-release ZFS under GPLv2 or BSD and merge the feature sets in the two filesystems.

Yes, I've been wondering myself how that one will go - ZFS was Sun's baby, but what's Oracle's view on it?

I didn't know both filesystems where (now) from the same owner. I'd actually suggest BSD though if they where looking to expand ZFS adoption. Hopefully the MBAs don't get a hold of it and lock it up as part of Solaris or a future Oracle enterprise product.
